In this report we discuss plans to carry out a longitudinal measurement study of changes in service-level reachability in the global TCP/IP Internet. We overview our experimental design, considerations of network and remote site load, mechanisms used to control the measurement collection process, and network appropriate use and privacy issues, including our efforts to inform sites measured by this study. A list of references and information on how to contact the Principal Investigator are included.
The global TCP/IP Internet interconnects millions of individuals at thousands of institutions worldwide, offering the potential for significant collaboration through network services and electronic information exchange. At the same time, such powerful connectivity offers many avenues for security violations, as evidenced by a number of well publicized events over the past few years. In response, many sites have imposed mechanisms to limit their exposure to security intrusions, ranging from disabling certain inter-site services, to using external gateways that only allow electronic mail delivery, to gateways that limit remote interactions via access control lists, to disconnection from the Internet. While these measures are preferable to the damage that could occur from security violations, taken to an extreme they could eventually reduce the Internet to little more than a means of supporting certain pre-approved point-to-point data transfers. Such diminished functionality could hinder or prevent the deployment of important new types of network services, impeding both research and commercial advancement.
To understand the evolution of this situation, we have designed a

study to measure changes in Internet service-level reachability over a period of one year. The study considers upper layer service reachability instead of basic IP connectivity because the former indicates the willingness of organizations to participate in inter- organizational computing, which will be an important component of future wide area distributed applications.
The data we gather will contribute to Internet research and engineering planning activities in a number of ways. The data will indicate the mechanisms sites use to distance themselves from Internet connectivity, the types of services that sites are willing to run (and hence the type of distributed collaboration they are willing to support), and variations in these characteristics as a function of geographic location and type...
